摘要： A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating i.e. decarboxylating, decarbonylating, and hydrodeoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. A sulfur containing component is added to drive the conversion preferentially through carbonylation and carbonylation with reduced hydrodeoxygenation. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties.

摘要： A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant oils, animal fats and oils, and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a diesel boiling range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.

摘要： A process is provided for producing low sulfur diesel having a high cetane number where the temperature and pressure requirements for obtaining low levels of sulfur is separated from the temperature and pressure requirements for improving cetane. In one aspect, a low pressure hydrodesulfurization zone and a high pressure aromatic saturation zone are employed to sequentially achieve the desired sulfur and cetane levels. In another aspect, the process first converts a diesel boiling range hydrocarbonaceous stream in a hydrotreating zone at conditions effective to produce a hydrotreating zone effluent having a reduced concentration of sulfur with minimal saturation of aromatics. Hydrogen is then admixed with the hydrotreating zone effluent, which is then reacted in a substantially liquid-phase continuous reaction zone substantially undiluted with other streams to effect saturation of aromatics to provide a liquid-phase continuous reaction zone effluent having an improved cetane number.

摘要： In one aspect, a hydrodesulfurization process is provided that selectively desulfurizes a hydrocarbon stream with minimal olefin saturation and minimal recombination of sulfur into mercaptans. In another aspect, the process includes a multi-stage reaction zone including at least first and second serial hydrodesulfurization reaction zones that sequentially remove sulfur from a hydrocarbon stream. In yet another aspect, the process is particularly suited to selectively desulfurize an olefinic naphtha hydrocarbon stream, such as FCC naphtha, steam cracked naphtha, coker naphtha, or other gasoline boiling hydrocarbon streams.
